A phreatic eruption was recorded at Mt. Pinatubo on Tuesday, Nov. 30, the Philippine Institute of Volcanology and Seismology (Phivolcs) confirmed.
Phivolcs said the eruption was likely driven by shallow hydrothermal processes beneath the edifice.
No reports of ashfall from communities of Zambales over which the eruption plume dispersed have been reported yet as of press time.
The public is cautioned to refrain from venturing in the vicinities of Pinatubo Volcano at this time.
The agency also advised all government units to prohibit entry into Pinatubo Crater until the source of the above explosion event has been determined.
Phivolcs also advised communities and local government units surrounding the area to be vigilant for both earthquake and volcanic hazards.
